Description
Technical field
The utility model belongs to underground coal mine fireproofing technique, more particularly to a kind of device for preventing goaf coal body spontaneous combustion.
Background technology
The freely burning fire consequence that causes the accident is serious in colliery, and Residual coal in goaf, coal breakage spontaneous combustion are easy to ignored, lead
Mine fire accident is caused, presence of the goaf due to losing coal, coal breakage, working face is distinguished and admirable to be leaked to goaf, causes coal body constantly certainly
Body oxidation heat liberation, in the case of reaching certain temperature, coal body itself starts to blaze up, due to be in goaf, be not easy by people and
Shi Faxian processing, cause coal-mine fire, threat to life and property safety.
Currently for goaf coal body spontaneous combustion, many measures, such as prediction of spontaneous combustion forecast, the inspection of underground beam tube are taken
Survey, closed preventing and treating leaks out, grouting fire extinguishing, nitrogen injection, gel fire extinguishing, pressure balance for air control etc., but can not be from basic
It is upper solution goaf problem on fire, due to it is on fire be it is unexpected, start be difficult arouse attention, until the condition of a fire is difficult to control, this
When disaster still lead to；Prior art CN106640175A sprays the mode of extinguishing chemical using the spheroid that bursts, and can only prevent and treat part
Region coal body spontaneous combustion, because the spheroid that bursts is in the hair for easily causing roof and floor unstability that accident occurs close to the explosion of the position of roof and floor
It is raw.
Utility model content：
The technical problems to be solved in the utility model：A kind of device for preventing goaf coal body spontaneous combustion is provided, it is existing to solve
There is technology fundamentally to solve goaf problem on fire, due to it is on fire be it is unexpected, start be difficult arouse attention, Deng Daohuo
When feelings are difficult to control, at this moment disaster still leads to；Prior art sprays the mode of extinguishing chemical using the spheroid that bursts, and can only prevent and treat portion
Subregion coal body spontaneous combustion, and the spheroid that bursts easily is causing roof and floor unstability that accident occurs close to the explosion of the position of roof and floor
The technical problems such as generation.
Technical solutions of the utility model：
A kind of device for preventing goaf coal body spontaneous combustion, it includes explosion spheroid；The explosion sphere installation is in goaf
It is interior；Temperature and Smoke Sensor are arranged on goaf back position；Shower nozzle is separately mounted to back and tunnel both sides；
Shower nozzle is connected by water pipe with sprinkler；Sprinkler is connected with fire extinguisher storage cavity；In fire extinguisher storage chamber body
Storage has extinguishing chemical.
Water pipe is the pipeline that sprays water with high pressure；It is high pressure spray device with sprinkler.
Sphere installation burst in goaf medium position.
The spheroid that bursts is temperature control explosion fire extinguishing spheroid.
Temperature and Smoke Sensor signal output part are connected with controller input；Controller output end and sprinkler
Control terminal of spraying water connection.
The beneficial effects of the utility model：
The utility model is by the sphere installation that will burst in goaf medium position, remote top plate and bottom plate；Avoid bursting
Spheroid is easily causing roof and floor unstability that the generation of accident occurs close to the explosion of the position of roof and floor；Further the utility model leads to
Smog and temperature sensor are crossed, the temperature in goaf and smog information are delivered into controller, when temperature exceeding standard, controller is defeated
Go out signal, the water spray control terminal action of sprinkler, the extinguishing chemical deposited in fire extinguisher storage chamber body is sent by sprinkler
Enter pipeline, sprayed by spout, carry out cooling fire extinguishing；Goaf problem on fire can not fundamentally be solved by solving prior art,
Due to it is on fire be it is unexpected, start be difficult arouse attention, until the condition of a fire is difficult to control, at this moment disaster still leads to；Existing skill
Art sprays the mode of extinguishing chemical using the spheroid that bursts, and can only prevent and treat subregion coal body spontaneous combustion, and the spheroid that bursts is on close top
The position explosion of bottom plate easily causes roof and floor unstability that the technical problems such as the generation of accident occur.
Brief description of the drawings：
Fig. 1 is the utility model structure diagram；
Fig. 2 is that the utility model packs structural representation.
Embodiment：
A kind of device for preventing goaf coal body spontaneous combustion, it includes explosion spheroid 4, and the explosion spheroid 4 is arranged on mined out
In area；Temperature and Smoke Sensor 1 are arranged on goaf back position；Shower nozzle 5 is separately mounted to back and tunnel
Both sides；Shower nozzle 5 is connected by water pipe 2 with sprinkler 6；Sprinkler 6 is connected with fire extinguisher storage cavity 7；Fire extinguisher
The storage internal memory of cavity 7 is placed with extinguishing chemical 3.
Temperature and Smoke Sensor 1 are arranged on goaf back position in the utility model, in order to more
The temperature and smog information in goaf are accurately measured, because the smog of goaf back and temperature ratio bottom plate and both sides
Will be high.
In order to improve the speed for spraying extinguishing chemical；Water pipe 2 is the pipeline that sprays water with high pressure；It is high pressure spray with sprinkler 6
Wetting system.
Explosion spheroid 4 is arranged on goaf medium position.The spheroid 4 that bursts is temperature control explosion fire extinguishing spheroid；Burst spheroid 4
Installed in goaf, medium position is in order to avoid having influence on the stabilization of goaf back and bottom plate when explosion spheroid 4 bursts
Property.
Temperature and the signal output part of Smoke Sensor 1 are connected with the input of controller 8；The output end of controller 8 is set with water spray
Standby 6 water spray control terminal connects.
